Steel 22MnB5 vs DP1470

Steel · grade comparison

Steel 22MnB5 and DP1470 are both steel grades. DP1470 is the stronger of the two: yield strength 1,120 MPa (162 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 195% more; tensile strength follows at 1,520 MPa (220 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 5.5% for DP1470, and DP1470 is harder (430 HB vs 160 HB). 22MnB5 runs hotter in service (250°C vs 200°C continuous) and DP1470 conducts heat better (42 W/m·K vs 32 W/m·K). On the shop floor, 22MnB5 machines more easily (good vs poor), 22MnB5 welds better (good vs fair), and DP1470 sits in a lower cost tier (budget, $) than 22MnB5 (standard, $$).

22MnB5Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

DP1470Choose it when strength drives the design, or when cost is the deciding factor.
